Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Fujifilm X-T10 and Sony A3000 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T10 has external dimensions of 118 x 83 x 41 mm (4.65 x 3.27 x 1.61″) and weighs 381 g (0.84 lb / 13.44 oz) (including batteries). Sony A3000 has external dimensions of 128 x 91 x 85 mm (5.04 x 3.58 x 3.35″) and weighs 411 g (0.91 lb / 14.50 oz) (including batteries).
Below you can see the front view size comparison of Fujifilm X-T10 and Sony A3000. Fujifilm X-T10 is clearly the smaller of the two cameras. Its body is 10mm narrower, 8mm shorter and 44mm thinner than Sony A3000.
Here is the back view size comparison of Fujifilm X-T10 and Sony A3000.
Now lets look at the top view comparison of Fujifilm X-T10 and Sony A3000.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T10 is 30g lighter than the Sony A3000 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Fujifilm X-T10 and Sony A3000 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Unfortunately neither Fujifilm X-T10 nor Sony Alpha A3000 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Fujifilm X-T10 and Sony A3000's LCD screens has the same diagonal size of 3".
On the other hand, Fujifilm X-T10 features a Tilting screen
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Sony A3000 has a fixed type screen which provides less flexibility in shooting positions compared to X-T10.
